Hi Adam, I just want to add myself to the list. In my case, I have a single ASMedia 1142 passed through:
04:00.0 USB controller: ASMedia Technology Inc. ASM1142 USB 3.1 Host Controller In my case, there's no ACS override, but I still experience the exact same problem. As long as the VM is shut down gracefully, I can boot the VM again, in case of crash or hard reset it won't boot anymore until host restart. I spent some time ago to somehow remove/reset/whatnot the controller in such a case - to no avail. I remember Alex Williamson being shocked, *shocked* I say, about ASMedia devices not behaving. The case was that when my controller was not passed through, but used by the host, it would prevent the system to properly suspend to RAM. I'd be very interested in knowing a way to archieve proper reset of the controller, but I fear there simply is none.
